I am 100% trad.
Using ladders obviously has its risks, but are alright if used properly, and you take your time in positioning it the prescribed angle (1 in 4) and you don't try to use it on surfaces which can cause it to slide (ie mossy flagstones or wet decking to name but two).
As you have a fear of heights, though, I would not recommend you use ladders, but use a trad pole where possible or go WFP.
Hope you do well,
John.
